Male mating behavior.
Caenorhabditis elegans male mating provides an excellent opportunity to determine how sensory perception regulates behavior and motor programs. The male-specific nervous system and muscles are superimposed over the general nervous system and musculature. Genetic screens and genomic approaches have identified male-specific and male-enriched genes as well as non-sex specific molecules specialized...
متن کاملFemale resistance to male harm evolves in response to manipulation of sexual conflict.
The interests of males and females over reproduction rarely coincide and conflicts between the sexes over mate choice, mating frequency, reproductive investment, and parental care are common in many taxa. In Drosophila melanogaster, the optimum mating frequency is higher for males than it is for females. Furthermore, females that mate at high frequencies suffer significant mating costs due to t...
متن کاملSize-dependent response to conspecific mating calls by male crickets.
Male sexual displays provide females with information that is crucial to their reproductive decisions. That same information is available to eavesdroppers, with potential consequences for both signaller and receiver. We present empirical evidence for size-dependent responses to intersexual communication by conspecific rivals. Acoustic features of a male house cricket's (Acheta domesticus) matin...
متن کاملMale and Female Competitive Behavior– Experimental Evidence
Male and female choices differ in many economic situations, e.g., on the labor market. This paper considers whether such differences are driven by different attitudes towards competition. In our experiment subjects choose between a tournament and a piecerate pay scheme before performing a real task. Men choose the tournament significantly more often than women. Women are mainly influenced by th...
متن کاملOrganization of mating behavior in male hamsters (Mesocricetus auratus).
Factor analysis was applied to standard measures of sexual behavior in 73 male hamsters (Mesocricetus auratus) as they interacted with hormone-primed females. The results suggest that 5 factors, or conceptual mechanisms, function in the organization of the behaviors observed in the first 2 copulatory series. Of these, the 3 that relate to the behaviors in the first copulatory series were compar...
